I thought i'd pass this on.
I'm running a Netgear PS121v2 usb print server. It had no issues under XP but within Vista / W7 there was a defect.
The driver for the V2 when installed came up as unsigned, therefore the installation wouldn't proceed any further.
I looked around the net, and a few people had found a workaround with installing the printer manually within Vista.
For me this still didn't work, as when the test page prints, it hangs one line from the end.
The netgear support site stated that the driver for the PS121v2 was compatible with XP through Vista 32 and 64bit.
So I took a chance and did the following:
Download the Drivers for the PS121v1
The difference from what I gather after reading some technical papers is that the firmware in the v2 allows for sharing of the multifunctions of multifunction printers.
The PS121v1 software is signed for Vista and installed no problem
I first connected the printer (an officejet 4100 series) to the PC and W7 found all the necessary drivers.
- impressive as HP's own site says that it doesn't support vista.
I then connected the printer to the PS121 on the router, and installed the PS121v1 drivers.
The drivers configure the existing printer setup to run on the printserver by modifying it's port details and settings.
Prints fine, with no glitches.
